One more thing. You can also connect a follower arm to it, as you can see in the video😄 润色

Additionally, as demonstrated in the video, you have the option to attach a follower arm to it. 😄

原来的句子没有语法错误，但稍微调整一下可能会更流畅：

"你还可以像视频中展示的那样，连接一个跟随臂😄"

Your original sentence is grammatically correct. However, here's a slightly refined version for improved flow:

"You can also attach a follower arm to it, as shown in the video. 😄"

Shoutout to @kamathsblog for the inspiration!
